What is the Best R-Value for an Attic in Florida?

The installation of insulation has evolved over the years, incorporating R-values into different materials. The higher the R-value, the better insulated the house will be. The Environmental Protection Agency (EPA) recommends an R-value of 30 to 60 for an uninsulated attic and 25 to 38 with existing insulation in Florida. ENERGYSTAR suggests an R-38 value for most homes, which is equivalent to approximately 12 inches of insulation.

If you don't have enough, you can measure the depth of the attic insulation with a ruler. It usually consists of a reflective material, such as aluminum foil, which is installed under the roof covering or inside the attic. If you're constructing a new home, you can consider installing insulation at the bottom of the roof covering and sealing the attic space, creating an “unventilated attic”. Johns Manville Kraft-Coated R-30 Insulator is a formaldehyde-free fiberglass insulation designed to provide efficient and safe insulation for attics and wood-framed ceilings.

This resistance, or R-value, refers to the performance of the insulation by measuring the resistance to heat flowing through the insulation over time. This is a very flexible roof insulator that adapts not only to the attic of the roof, but also to other areas, such as floors and walls. This insulation is specifically designed for attic insulation projects in new and existing homes. In two-story houses, floor beams are not always sealed from adjacent attic spaces rather than single-story spaces and attic air is right next to the roof. It also comes with an advanced fire resistance rating, so the risk of a fire spreading is minimal if attic insulation is used.

It's very important to understand that how insulation is installed is almost as important as the R value. We offer attic insulation installation, air sealing, and insulation removal services to help you reduce your home's energy consumption and maintain a consistent temperature. Blown insulation, also known as loose-fill insulation, is one of the most popular insulation systems, making it ideal for attics and small spaces that are difficult to access. Attic insulation is critical because more heat passes per square foot through the roof than in any other structure in a home. R-30 insulation with kraft coating is a reliable option for homeowners looking to improve their home's energy efficiency and increase thermal comfort in their attics and roofs.

Fiberglass blocks provide good thermal insulation and can be easily installed in attics or between exposed roof structures. You can measure the thickness of the attic insulation with a ruler and multiply it by its R-value to get an insulation rating.
